(This section describes how to scan a barcode inside a PhoneGap app.An alternate approach scans a barcode from a normal HTML/JavaScript Web page.[7])

Several people use the Barcode plugin to work with barcodes in their PhoneGap application.[8][9][10][11][12][13]

If it doesn't yet support the barcode format you want to use,
you may need to build your own custom PhoneGap plugin,
perhaps starting with
Barcode development in Java.[14]
